To all whom it may concern/.-

Be it known that I, JOHN 0. FORD, of Beverly, in the county of Macon andState of Missouri, have invented a certain new and useful Machine forSplitting and Rewinding Roll-Paper, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification.

This is a machine by which a mill-roll is unwound and is rewound uponanother roll and at the same time out into narrower widths. Therewinding shaft has circumferential grooves to allow the edges of thecutters to pass through the paper, and is constructed for diametriccontraction to allow of the easy removal of the rolls from it.

Figure I is a plan of'the machine with part in horizontal section. Fig.II is a side elevation. Fig. 111 is a longitudinal section at III III,Fig. I. Fig. IV is a detail elevation showing one of the rotary cutterswith its supportingarm, &c., the winding -shaft being in transversesection. The full lines show the parts in position for the beginning ofthe rewinding of the paper and the broken lines indicate the position ofthe parts after the rewinding has been completed. Fig. V is an enlargeddetail section at V V, Fig. II. Fig. VI is a side view of one of therotary cutters and its supporting-arm. Fig. VII is a section at VII VII,Fig. VI. Fig. VIII is a detail front elevation showing the means for theendwise adjustment of the mill-roll shaft. Fig. IX is an end elevationof one of the brackets supporting the rod on which the cutter-arms aresustained. Fig. X is a side elevation of the bracket. Fig. XI is atransverse section of the winding-shaft at XI XI, Figs 1' and XIV. Fig.XII is an end View of the winding-shaft with the screw collar or nutremoved. Fig. XIII is a side view of the winding-shaft Fig. XIV is anenlarged detail longitudinal section of'the windingshaft at XIV XIV,Fig. XIII. I

The sides of the main frame are'seen at 1. They are secured together bytransverse bars 2 and 3. p

at is the drive-shaft carrying a belt-pulley 5 to receive a drive-belt.The shaft 4. has bearing in boxes 6 and 7. The box 6 is secured to oneof the sides of the main frame and the box 7 to a bracket 8, attached tothis side. The shaft 4 has a socket 9 formed to receive thefrusto-pyramidal end 1.0 of the rewinding 5 5 or expansion shaft 11. Theconstruction is such that when the end 10 is within the socket therewinding-shaft is forced to turn with the drive-shaft. Therewinding-shaft has a round end 12 turning in a journal-box 6o 13 on oneside of the main frame. The end 12 extends beyond the journal-box togive means for lifting that end of the shaft. The cap of the box 13 ishinged at 14, so that it may be thrown back to allow the removal of theshaft. It will be seen that when the cap of the box 13 is thrown backthat end of the shaftmay be lifted from the box and the end 10 drawn outof the socket 9. The middle part of the rewinding or expansion 71 shaft11 (or that part upon which the paper rolls are wound) has an interioror central portion 15, which is square in cross-section and of equalsize from end to end, the opposite sides 16 being parallel to eachother. To 75 each side 16 is fitted a strip 17, whose inner sides 18 areparallel with the sides 16 of the central portion. The outer sides ofthe strips 11 are so curved or convexed that when they I are in theirouter position they form together a true cylinder concentric with-theaxis of the shaft. The surface strips 17 are connected to the shaft byscrews 19, which pass through I counterbored slots 20, the screw-headsocc'u pying the counterbores and not projecting ber yond the outer faceof the strips 17. The

ment on the strips 17 thus have endwise move core 15 of shaft 11.

At 21 are inclines on the part1 11, and at 22 are inclines on each oftlrestrips o 17. In a long winding-shaft theremay be three or more setsof these inclinessayone set near each end and one set at the middle.These inclines bear upon each other, so that when the strips are movedtoward the end 10 5 they will be forced outward as far as the screwspermit.

23 is a collar fitting the end 12 of the shaft 11 and held in place by aset-screw 24. The ends of the strips abut against this collar, and :00thus the strips are restrainedfrom endwise movement and held in theirposition, as seen 5 of tlfe state V in Fig. XIV. The other ends of thestrips 17 bear against a screw collar or not 25, which screws upon theshaft. (See Figs. I and XIV.) \Vhen it is desired to place the strips 17in their inner position, the shaft 11 is removed from the machine, thecollar 23 made loose, and the nut 25 screwed inward to push the stripstoward the end 12. This relieves the bearing of the inclines 21 and 22and the strips approach the part 15, thus decreasing the diameter of theshaft 11, composed of the part 15 and strips 17. This position of thestrips is shown in Fig. XIII. \Vhen winding the rolls of paper upon thewinding-shaft 11, the shaft has its larger diameter. To allow the easyremoval of the paper rolls from the shaft, it is contracted to itssmaller diameter, as described, when it may be easily drawn from therolls. The nut has holes 26 for the application of a wrench, by which itmay be 1 shaft 51, and which are forcedv into the ends I of the axialpassage through the roll and serve to center the roll and to hold itfirmly turned. The strips 17 have circumferential grooves 27 to receivethe edge of the cutters, by which the broad roll of paper is cut intonarrow rolls. The boxes 6, 7, and 13 are shown to be longitudinallyadjustable by means of ing screw studs or bolts 29. AtSO are screwsturning in lugs 31 upon the side pieces 1, the

ends of the screws screwing into the boxes.

32. are brackets attached tolthe boxesG and 13 and having at their outerends eyes 33, throughwhich passes a shaft 34E. The cutter arms35 arestrung on thisshaft. The eyes 36 of the cutter-arms have set-screws 37,which may be made to bear on the shaft 34 and hold the armsin posit-ionupon the bar. The arms. 35 are forked at 38, and within the fork is.the. rotary cutter, which turns on an arbor 1 ot the mill-roll shaft andto give means for the endwise adjustment of the shaft, a projecting lip.67 of a sliding block 68 is constructed to engage in a circumferentialgroove j (36 of the pulley. 1 guide 69'and carries a hand-screw 70,which 5 turns in bearings of the block andscrews into the guide, so thatby turning the hand-screw the block 68 is moved inward and outward, andwith it the pulley 58 and. mill-roll shaft.

39,, passing through the ends of the fork. The cutter consists of twodisks 40, with a circular knife 41 of thin steel interposed betweenthem.

At 42 are. screws by which the disks are fastened together.v The edge 42of the cutter is preferably serrated.

In order topress the cutters upward toward the winding-shaft 11, aweighted arm 43 is attached to the shaft, the weight 44: sliding on theshaft and being held in place by a setscrew 45. (See Figs. LII, and IV.)The construction is such that the pressure of the cutters against thepaper may be regulated by moving the weight on the arm. The armhas adownward projection or arm 46, in which turns a screw whose point bearsagainst the framel when the cutter is in its upper position, and thusprevents the cutter from coming in contact with the windingshaft. Thisposition of the parts is shown in full lines in Fig. IV. To sustain thebar 34in its highest position and hold the cutters in their lowerposition, a drop-latch 47 is pivoted to the arm. or projection 46, saidlatch having a notch 48 upon the lower edge at its free end, in whichnotch engages-a stud or pin 49, projecting from the main frame. By thismeans 3, which may be of wood or of metal.

the cutters are held out of contact with the rolls of paper while thewinding-shaft is being removed from its bearings for the removal of therewound rolls of paper therefrom.

The means for supporting and adjusting the mill-roll 50 will now bedescribed.

51 is a shaft, which is passed axially through the mill-roll and whichhas hearings in the boxes 52. These may be thrown back and the shaftlifted from its bearings for insertion in a mill-roll. The boxes areattached to the frame in a similar way to the boxes 6 and 13, so as toallow their longitudinal adjustment, and, like said boxes, they areconnected by screws 54 to lugs 55 upon the main 1 frame, so that byturning the screws either or both ends of the mill-roll shaft may be 3moved outward or inward.

56 are conical collars, which slide on the upon the shaft, the collars.being held in place by set-screws 57. the slots 28, through which passthe attach- 1 58 is a pulley upon the shaft 51,said pulley being securedon the shaft by a. set-screw 59.

60 is a brake-strap, which bearson the surface of the pulley. Oneend ofthe strap is pable of sliding on the horizontal arm of the ilever, soas. to adjust the pressure. of the brake upon the pulley. VIII.)

(See Figs. I, II, and

In order to prevent the endwise movement The block 68 works. on a Fromthe mill-roll the paper 71 passesto and over the top of one of the fixedtension-bars The tension-bars are rounded at the upper edge to avoidinjury to the paper. Between the two fixed tension-bars 3 is a movabletensionbar 72, which may be similarly formed in every respect to thebars 3, but with the under edge rounded, as this is the edge against 1which the paper bears- The bar 72 is rounded at the lower edge for theavoidance of injury to the paper. From the under side of the bar 72 thepaper passes to and over the other fixed bar 3, from that to and beneatha roller 73, and from that to the winding-shaft 11. The bar 72 androller 73 are made vertically adjustable by independent adjustingdevices at the sides of the machine, so that IIO not only can thetension upon the paper be increased by moving the bar 72 downward, butin case the paper on the mill-roll should bag in any degree at one edgeby lowering that end of the roller 73 the tension may be equalizedacross the paper.

The ends of the bar 72 are moved vertically by the following devices:The ends 74 of the bar have bearing in vertical guides 75. At each endof the bar 72 is a depending cograck 76, which engages with a cog-wheel77 upon a shaft 78, carrying a hand-wheel 79. (See Figs. I, II, III, andV.) It will be seen that by turning the hand-wheel the bar may be raisedor lowered. is a locking-lever having a notch or catch adapted to engageeither of the handles 81 of the hand-wheel 79 locking-lever inward tothe hand-wheel.

and hold the wheel in any position in which it may be placed. 82 is aspring drawing the (See Figs. I and II.) The gudgeons 83 of roller 73have bearing in boxes 84, working in vertical guides or housings85. 86are hand-screws threaded in the tops of the housings and having bearingat the lower ends in the boxes 84. The operation of the machine is asfollows: The mill-roll shaft 51 is removed from its bearings 52 andinserted in the mill-roll and the cones 56 forced into the axialopenings and the set-screws 57 screwed tight. The shaft 51 is thenplaced in its bearings. paper is passed from the roll beneath one fixedbar 3, under the movable bar 72, over the other bar 3, beneaththe roller73, and to the windingshaft 11. The rotary cutters have been placed inthe proper position. on the shaft 34, so that the cutting-edges 41 willenter one of the circumferential grooves 27 of the winding-shaft. Anyunused cutters may be allowed to hang vertically on the shaft 34. Themachine may now be put running and the paper will be wound on therewinding-shaft and at the same time out by the cutters. As the diameterof the paper rolls upon the rewinding-shaft increases the peripheries ofthe disks 40 bear against the paper roll and the cutters are thusgradually forced downward, the weighted arm 43 being lifted. W'hensuflicient paper has been wound on the rewinding-shaft,the machine isstopped and the winding-shaft removed from themachine. and the nut 25screwed forward on the shaft to cause the strips 17 to fall in anddecrease the diameter of the shaft, so that the paper rolls may easilybe removed from it. I This machine may be associated with printing-pressor other machine to cut the paper longitudinally, the press or othermachine occupying the position of the 1nill-roll. In place of the nut 25upon one end of the winding-shaft a collar may be fixed upon the shaftor a movable collar similar to the collar 23. The collar 23 may be madeto screw on the shaft in place of being fixed thereon by The set-screw24 is then made loose a set-screw. The preferred construction has,however, been shown.
